February Medium/Long Range Disco

A couple of things here:

 

1. The problem is NOT the eastern PV "racing" away from us. In fact, the mess this weekend allows for the deepest low anomalies toward the 50-50 position yet. It MUST lift out in order for it to snow in the Mid Atlantic, otherwise it gets squashed.

 

2. The problem PV is the western PV. It drops down from the North Pole due to the N PAC block. It comes down and sits in N-C Canada the entire run basically after it drops in. This sits on the western side of the "west NAO-light" block. Some of the modeling insists that it will be assertive enough to ruin confluence on its on.

 

Usually in a classic 50-50 low / coastal storm scenario, the confluence locks in anyway as the 50-50 low lifts because there is a ridge across W-C North America. That makes this upcoming case not quite classic SHOULD the western PV become a player.

 

Might be worth looking into events and seeing if any had this western PV feature to the block.

 

2/22/86 is pretty close....you could also make a case for 2/26/10

Yea, it was pretty fleeting in the big picture. But it took us a while to erase the model porn from our minds as it became clear the streams weren't going to dance. 

 

Ji, is the jma any good? I never even look at it. I broker a personal rule and looked at the canadian today. Time is short. I'm just going to hug whatever. Right now the jma is the front runner so i'll go with that. 

The JMA, like the CMC does not have great verification scores, but when a lot of the lesser globals start to pile on to a solution and the euro is in their camp, it does start to build a case.  Safe to say all the guidance is in support of a gulf system coming up the east coast next week and there will be cold air around in front.  Thats a pretty good starting spot imho but the rest is details we can't expect to iron out for a few days yet.

Thanks man, I'll check them out; I knew I could count on you! ;)

 

I'm really devoted to finding some snow for DC. Whether you believe me or not is irrelevant.  :P

Late Feb is where it's at.  Because early Feb is mostly cooked. :P

We got back to back 4" storms 2 days apart...and a 2" storm 2 days after that...not sure how the northeast did...

 

EDIT - I know in the upcoming scenario the PV is further east and the faux -nao is further west

That is pretty darn good. The only problem is the North Atlantic. 1986 clearly had a classic -NAO progression while  this year is sort of, well, not classic lol.

the 2 weeks from 2/22 to 3/8 have been "productive" for us recently for whatever reason..events 6 out of the last 9 winters...we may have even outperformed climo over the last 10 years or so?

 

MBY since 04-05

 

3/1-2/09 - 7.5"

2/24/05 - 4.5"

2/25/07 - 4.25"

2/28/05 - 3.25"

3/7/07 - 1.75"

3/8/05 - 1.0"

2/21-22/11 - 0.75"

2/27/10 - 0.25"

3/6/13 - 0.25"

EURO ens mean looks like it agrees with the OP, it seems colder though and a bit farther East

 

I dunno if its colder... 144 decent CAD going on and by 168 on the EPS mean the 0C line is over DCA.. but then drops back SE some by 192

 

Though the low is weak... like 1008-1012mb

EPS is better than last night. Seems like it is narrowing down the spread with precip. Surface and 850's colder overall but as yoda pointed out, 850's are borderline @ 168. Enough members with a close track. Mixing on the table for sure. But it is slightly further east than the op as a whole. It's a good run. 

 

The control run buries us pretty good too.

There's actually a little secondary peak in that period .. shows up in a few spots that I've looked. At least on the lower end scale of accum.  I always try to cancel winter early but climo remains fairly favorable through at least the first week of March.. you may be right though haven't looked per se at that.

I really do love modeled snow....their is an excitement behind it and your imagination can go wild. It would just be nice if some of the modeled snow actually fell onto my grass

it's hard to say this, I know I'll be scorned by those either out of or not yet completed detox....but I agree 100%

I have no grass, since I live in an apartment.  I wish modeled snow would fall on my modeled grass.

for giggles, look at 360 hrs on the control run with the PV making a final appearance for the season

I bet you that model will show it in the coming days phasing with the trough out in the west

not saying it will, in fact, happen, just that the model will show it
